Wolves (Canus lupus) do not seem to have ever been common in the southern Cascade region and are now gone from the area.
In the early 1900's,
predator control programs largely exterminated this species in the region and the last recorded wolf kill in the State of Oregon was in 1927 east of Fort Klamath by Biological Survey
predatory animal hunters.
